In any of the tables described in Patent Documents 1 to 3, the top plate needs to be processed, which increases the cost.
In addition, if the top plate is provided with a recess or a protrusion, the outer shape of the top plate changes when the table is used as a normal table that does not require wiring of cords, resulting in poor appearance.

  Like the table described in Patent Document 4, when a spacer is provided on the side edge of the top plate so as to be detachable, or when the legs of the tables arranged opposite to each other are connected by a spacer, when wiring is necessary or unnecessary, The spacer must be attached and detached each time, and the work is troublesome.

  In addition, it is necessary to perform special processing for mounting spacers on the upper end of the table legs, which cannot be used in common with normal table legs that do not require spacers. This increases manufacturing costs.

  The present invention has been made in view of the above problems, and without changing the outer shape of the top plate, a gap is formed between the top plate and the wall surface or between the facing surfaces of the top plates, and the lower side of the top plate. The cords can be easily wired, the spacer can be easily changed between the use position and the non-use position when wiring is necessary or unnecessary, and the top plate and legs are processed significantly. The purpose is to provide a table that is not necessary.

According to the present invention, the above problem is solved as follows.
(1) A spacer member having an upward projection on the upper surface of one end on the lower surface of the side end of the top plate, a non-use position where the entire spacer member is located below the top plate, and the upward projection on the top plate It is provided so as to be changeable in a use position that protrudes from the side edge of the plate and abuts or approaches the end surface.

(2) In the above item (1), when the spacer member is in the non-use position, a holding hole is provided on the lower surface of the top plate so that the upward projection can be loosely fitted from below.

(3) In the above item (1) or (2), the spacer member is elastically deformable in the vertical direction.

(4) In the above item (3), a finger-hanging piece projecting outward is provided below the upward projecting portion of the spacer member.

(5) In any one of the above items (1) to (4), the spacer member is provided so as to be horizontally rotatable around the other end on the side opposite to the end provided with the protrusion.

(6) In the above item (5), an arc-shaped groove through which the upward protrusion can pass is provided on the trajectory of the upward protrusion on the lower surface of the top plate.

(7) In any one of the above items (1) to (4), the spacer member is provided so as to be slidable inward and outward of the top plate.

  According to the first aspect of the present invention, only by moving the spacer member to the use position, a required gap is formed between the side edge of the top plate and the wall surface or the top plate of another table. Since wiring can be made downward, it is not necessary to provide a recess or protrusion on the top plate as in the prior art, and the appearance of the top plate is prevented from deteriorating.

Moreover, since the spacer member can be positioned below the top plate when not in use, it does not get in the way and the appearance of the table does not deteriorate.
Furthermore, since it is not necessary to perform significant processing for attaching the spacer member to the leg body or the top plate, they can be shared with other tables and the cost can be reduced.

  According to the second aspect of the present invention, it is possible to prevent the spacer member in the non-use position from moving to the use position due to illusion, and the amount of protrusion of the spacer member from the lower surface of the top plate when not in use Can be reduced.

  According to the third aspect of the invention, the spacer member is elastically deformed downward to move the upward protrusion at the use position to the non-use position, or the upward protrusion from the inside of the holding hole is detached from the use position. Can be moved easily.

  According to the invention of claim 4, the spacer member can be easily elastically deformed downward by placing a finger on the finger-hanging piece.

  According to the fifth aspect of the present invention, the spacer member can be easily moved between the non-use position and the use position, and the spacer member can be horizontally rotated along the lower surface of the top plate. The protruding dimension of the spacer member from the lower surface can be minimized.

  According to the invention described in claim 6, since the upward protrusion rotates between the non-use position and the use position along the arc-shaped groove on the lower surface of the top plate, it is necessary to elastically deform the spacer member downward. In addition, the rotation operation is facilitated, and the selection range of the material of the spacer member is expanded.

  According to the seventh aspect of the invention, as in the fifth aspect of the invention, the spacer member can be easily moved and can move horizontally back and forth along the lower surface of the top plate. The protruding dimension of the spacer member can be minimized.
